What is a SIM Lock

Some Carriers activate SIM lock on some of their Iphones and restrict them to their network and services. SIM locked Iphones will work only with that Carrier's SIMs and services. These phones does not work with other carriers unless this lock is removed.

How is SIM Lock Activated?

When the devices are programmed at the factory, the SIM Lock is activated by the manufacturer, upon the request of the carrier who sells the device. SIM locked devices are programmed to work with specific providers only and when other providers' SIM cards inserted, device checks whether the SIM card belongs to authorized provider. If an unauthorized carrier's SIM is used, your Iphone will display "SIM Not Supported" or "SIM Invalid" message. This informs you that other Carriers' SIM cards will not work with the device as long as this lock is not removed.

Why Providers Lock Phones?

Many Carriers offer various promotions and discounts to make their services more attractive and to encourage mobile users to use their services. These may be the discounts they offer for phones, or may be mobile plans or discounted mobile tariffs.
In order to guarantee that they can redeem these discounts, they want their devices are used with their own services, so they aim to keep users on their network by activating the SIM Lock for certain periods of time.
This is not the only reason. Losing phones in shops or during shipping is also a problem for them. In order to prevent this, they aim to make these phones useless by locking them to their network when necessary.
The above reasons may be useful for Carriers, and it is possible to qualify some of them, but this may put people who make their payments on time or who buy second-hand phones, in a difficult situation.

What Does SIM Lock Mean for Users?

The main advantage for users is getting a discount phone. SIM Locked phones are usually sold cheaper than others or offered with more affordable tariff plans.

If you don't want to change your carrier, it won't be an issue as long as you use their services.

However, if you are not satisfied with your carrier and want to switch to another one and use other companies' services, SIM Lock will prevent it.

If you want to sell your phone as second hand and if the buyer can not remove the lock, they will not be able to use other Carriers' SIM cards and services.

When you travel to another country and want to use a local prepaid SIM card instead of using expensive roaming plans, SIM Lock will not allow this.
